متن کاملElectroweak Bubble Nucleation , Nonperturbatively
We present a lattice method to compute bubble nucleation rates at radiatively induced first order phase transitions, in high temperature, weakly coupled field theories, nonperturbatively. A generalization of Langer’s approach, it makes no recourse to saddle point expansions and includes completely the dynamical prefactor. We test the technique by applying it to the electroweak phase transition ...
متن کاملSurface bubble nucleation stability.
Recent research has revealed several different techniques for nanoscopic gas nucleation on submerged surfaces, with findings seemingly in contradiction with each other. In response to this, we have systematically investigated the occurrence of surface nanobubbles on a hydrophobized silicon substrate for various different liquid temperatures and gas concentrations, which we controlled independen...
متن کاملFluctuation corrections to bubble nucleation.
The fluctuation determinant which determines the preexponential factor of the transition rate for minimal bubbles is computed for the electroweak theory with sinΘW = 0. As the basic action we use the three-dimensional high-temperature action including, besides temperature dependent masses, the TΦ one-loop contribution whcih makes the phase transition first order. The results show that this term...
متن کاملNumerical Aspects of Bubble Nucleation
The effective potential determines the vacuum state of a quantum field theory. When radiative corrections are included or, if one constructs the finite temperature version of field theory the (effective)potential may have two minimum, one of which is lower than the other. The ’higher’ minimum is referred to as the false or metastable vacuum. The global minimum is the true vacuum state of the th...
